SPECIFICATION forming part of Letters Patent No.328,733, dated October20, 1885. Application filed November 18, 1884. Serial No. 148,209. (Nomodel.)

To all whom it may concern:

Be it known that I, WILLIAM WARDMAN, of Bristol, in the county of Bucksand State of Pennsylvania, have invented a new and useful Improvement inSpindles for Cap Spinning and Twisting Machines, of which the followingis a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a central vertical section of my invention in place upon aspindle fixed in a rail shown in side elevation. Fig. 2 is a sideelevation of the whirl and slotted tube. Fig. 3 is a side elevation of abobbin. Fig. 4 is a plan of the bobbin-socket case. Fig. 5 is asectional plan view of the bobbin-socket, taken through the line or m,Fig. 1. Fig. 6 is a sectional plan view of the bobbin-socket, takenthrough the line y y, Fig. 1.

The object of this invention is to provide spindles for cap spinning andtwisting rnachines constructed in such a manner as to increase thequantity and improve the quality of the work done by such machines, andat the same time lessen the expense of running the machines.

The invention consists in the construction and combination of partshereinafter described and claimed.

A represents the rail to which the base of the dead-spindle B isattached. D is the whirl, which is attached to the lower end of the longtube E, placed upon the spindle B, the said tube and whirl resting on ashoulder, O, on the base of the said spindle.

The tube E and spindle B pass through a hole in the lifter-plate, F, andthrough the bobbinsocket G, which rests upon the said lifter-plate, andis kept in contact with it by the stop H, attached to the saidlifter-plate F, and which overlaps a flange, I, formed around the lowerend of the said socket G. The lower part of the socket G fits upon thetube E, and is perforated for the passage of the stop-pin J, attached toorformed upon the free end of a spring, K, the other end of which issoldered, riveted, or otherwise secured to the said socket G. The pin Jenters and slides up and down in a long vertical slot, L, formed in thetube E, so that the socket G will be carried around by and with thetubeEand whirl D in their revolution, while being free to move up anddown upon the said tube. The upper part of the socket G is enlarged toreceive the base-flange of the bobbin M, which is placed upon the tube Eand rests upon the shoulder of the said socket G. Around the base flangeof the bobbin M is formed an annular groove, N, to receive the roundedinner ends of the pins 0, which pass in through perforations in theopposite sides of the enlarged upper part of the socket G, and areattached at their outer ends to the free ends of springs P. The springsP are placed in an annular groove formed around the enlarged upper partof the socket G, and are secured to the said socket by solder, rivets,or other suitable means, so that the bobbin M will be made to move upand down with the socket G.-

The socket G is surrounded and protected by a tubular case, Q, thelowerend of which is flanged and is secured to the lifter-plate F by screwsor rivets, so as to be kept in place.

R is the cap, which is made and carried upon the upper end of thespindle B in the ordinary manner.

\Vith this construction the whirl D and tube E always revolve in thesame place, while the socket G and bobbin M are carried up and downbyand with the lifter-plateF to lay the yarn upon the bobbin, so thatthe drivingbands will always have the same tension, and

will thus be more durable and will drive the bobbins at a uniform speed,avoiding slack and uneven twist and producing a better quality of yarn.By this construction, also, the bobbin M can be made much longer and canhave a longer traverse than when the said bobbin and the tube E andwhirl D move up and down together, so that each bobbin will contain moreyarn than the bobbins heretofore used, saving much time lost in changingbobbins, and thus increasing the amount of work done by the machine.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination, with the dead-spindle B, the whirlD, and the lifter-plate F, of the long tube E, having longitudinal slotL, and the bobbin-socket G, having spring-pins J K and O P to engagewith the slotted tube E and the base of the bobbin, substantially asherein shown and described, whereby the whirl and whereby the saidbobbin-socket is covered and long tube can revolve in the same placeWhile protected, as set forth. the socket and bobbin are moved up anddown by the lifter-plate, as set forth.

2. The combination, with the lifter-plate F and the bobbin-socket G, ofthe case Q; substantially as herein shown and described,

WILLIAM WARDMAN.
